Description

A partial-wave analysis of the (3π)0 system produced peripherally in the reaction K-p→π+π-π0Λ at 4.2 GeV/c is presented. The observation of the weak Λ decay allows a determination of all the transversity production amplitudes except for two phases. The production of known resonances having decay modes other than 3π is used to test the isobar model ansatz. Significant ω(783), phi(1020) and A2(1310) production is observed. The spin parity of the ω*(1675) is established as 3-. No evidence for production of other resonances, such as axial vector-mesons, is found. (Auth.)
